10 Best Electric Wall Heaters

The Devola Designer WiFi Enabled Electric Glass Panel Heater offers a powerful 2500W output, making it suitable for heating medium to large rooms efficiently. It features a built-in thermostat and a 24-hour, 7-day digital timer, allowing precise control over your heating schedule. One of its standout features is the WiFi connectivity, enabling remote operation via a smartphone app compatible with Alexa — great for modern smart homes. The heater is IP24 rated, meaning it's splash-proof and safe for use in bathrooms or kitchens, enhancing safety. It also has an auto shutoff feature, adding peace of mind.

Installation is versatile since it comes with both wall mounting brackets and feet, so you can fix it to the wall or use it freestanding and move it around as needed. Its ultra-slim, black glass panel design is sleek and modern, blending well with most interiors without being noisy during operation. Energy efficiency is another highlight, meeting the latest Eco Design standards, which should help keep running costs reasonable. Weighing 8.5 kg and sized at 85 x 47 x 7.5 cm, it’s fairly compact for a 2.5kW heater.

It requires connection to a 2.4GHz WiFi network initially, which might confuse some users with dual-band routers. The 1.5m cable with a UK plug is convenient, but the heater is only rated for indoor use and is not suitable for outdoor settings. The included 1-year warranty (extendable to two years upon registration) and free lifetime support add value and reassurance. If you want a reliable, smart, and stylish electric heater with flexible installation and good safety features, this Devola model is an excellent choice, especially if you appreciate modern smart home integration.

The Devola Wifi Enabled Smart Electric Glass Panel Heater is a versatile 2000W heater suitable for indoor use in rooms up to about 22 square meters. One of its standout features is the precise electronic thermostat that keeps the temperature steady within half a degree, helping you save on energy bills by switching on and off automatically. You can control it remotely via the Tuya Smart App compatible with Alexa and Google, which allows creating heating zones and scheduling timers for convenience. It offers two heat settings (1000W and 2000W), giving you flexibility in energy use.

From a safety standpoint, this heater has an IP24 rating, meaning it’s splash-proof and safe to use in bathrooms or kitchens, which adds peace of mind. It comes with wall mounting brackets but can also be used freestanding, offering installation flexibility. The slim glass panel design looks modern in black and should fit well in most rooms without taking up much space. Electric panel heaters like this are generally quiet, making it suitable for bedrooms or living areas. The weight is moderate at 8.5 kg, making installation manageable but possibly requiring two people.

One consideration is that the initial WiFi setup requires connecting to a 2.4GHz network only, which might be a minor hassle if your home uses 5GHz WiFi predominantly. Also, the heater is designed for indoor use only and might not be suitable for very large rooms or spaces needing rapid heat. The warranty is one year, extendable to two with registration, which is fairly standard but something to consider. This heater suits those seeking smart control, energy efficiency, and a sleek design in an indoor electric wall heater, especially in medium-sized rooms, with practical safety features and flexible installation options.

The BTGGG 2000W Electric Oil Filled Radiator is a solid choice if you're looking for a wall-mounted heater that is energy efficient and space-saving. Its 2000 watts make it powerful enough to heat rooms up to around 24 square metres, which is suitable for typical living rooms or bedrooms. The built-in thermostat with a temperature range from 7 to 35°C helps keep the room comfortable without wasting energy. You can also set the 7-day or 24-hour timer to automatically control heating times, which adds convenience and can reduce running costs.

Thanks to the radiator’s oil-filled design, it continues to radiate heat evenly even after being switched off, which is more efficient than many standard electric heaters. The three heating modes — Comfort, Economy, and Anti-freeze — allow flexibility for different needs, whether you want warmth, energy savings, or protection from freezing. Safety is well-covered with features like an IP24 waterproof rating, overheat protection, and a child lock function on the LED control panel. These aspects make it a reliable option for homes with children or pets. Installation is straightforward since it comes with a wall bracket and a UK plug, though the 1.2-metre cable length might require positioning near a socket.

One possible drawback is that oil-filled radiators typically take a little longer to warm up compared to fan heaters, so if you need quick heat, this might not be the best fit. Also, while the product size is quite slim and unobtrusive, the black colour and fins design might not blend seamlessly with all room decors. This heater is well suited for those who want a quiet, efficient, and safe heating solution for indoor spaces, especially if you prefer a wall-mounted option that saves floor space and offers programmable heating schedules.
